    ulimit官方描述
    Provides control over the resources available to the shell and to processes started by  it,  on  systems that allow such control. The -H and -S options specify that the hard or soft limit is set 
    
    for the given resource. A hard limit cannot be increased once it is set; a soft limit may  be  increased  up  to  the value of the hard limit. If neither -H nor -S is specified, both the soft and 
    
    hard limits are set. The value of limit can be a number in the unit specified for the resource or one of the special values hard, soft,  or  unlimited,  which  stand  for  the  current hard limit, 
    
    the current soft limit, and no limit,  respectively.
    If limit is omitted, the current value of the soft limit  of  the  resource  is  printed,  unless  the  -H  option is given.  When more than one resource is specified, the limit name and unit are  
    
    printed before the value.
